Need help with programming double solenoids

[noah10001]

Alright this worked! Now when i push a button my air cylinder goes all the way up or all the way down. Is there any way to have an in-between..I attempted to code the right stick on the xbox controller but said there were two different data types

Simple answer: no. Pneumatic solenoid valves are two-state devices. There is no middle ground.

Complicated answer: with sufficient analysis and design, one can devise a way to use multiple solenoid valves and flow restrictors to cause a pneumatic cylinder to retract or extend an arbitrary amount. It will move in a spring-like fashion due to external forces, so some sort of feedback on its actual position would be helpful.

When i click the buuton it is one-and-done.We want the button while pressed to flow and when released no flow anyway for this?

Do you mean like this example?
The solenoid here is Forward only as long as the button is held.

So is there a way to lift a joystick to lift the cylinders some and then let go and it will hold that pressure until i move to joystick again?

You can't do it with a double solenoid valve connected to a typical pneumatic cylinder.

It is possible to do something like what you are asking by using multiple solenoid valves connected in creative ways, but it is not something you will find an off-the-shelf solution for. However, it will be very difficult to make it meet the pneumatics rules, which require that the working pressure never exceed 60 psi.
